WALL CONSTRUCTION.

Application lei February 16, 1926. Serial No. 88,576.

This invention relates to improvements in the building art and particularly to partition wall construction in Class A fire proof buildings.

The commonly used four inch corridor walls andthe two inch partition walls in this class of building are now usually constructed with small channel iron studs to which expanded metal lath is fastened by various methods, the plaster being then vadhered over the metal lath. This type of wall is costly in material and the labor cost of installation is also high.

Plaster board of that type wherein a call cined gypsum core is adhered to two surface sheets of strong paper has been found to be very admirably adaptable for use in various forms of plaster lat-h in such Class A build ings, since it is substantially fire proof, light, durable and cheaper than metal lath. Some difliculty however' has been encountered in nding ways and means for mounting it successfully and cheaply on the studs. I have been working upon various methods of doing this and this present invention and application is directed to that subject matter.

In the drawings presented herewith similar characters of reference indicate corresponding parts in the several views:

Inthe drawings Fig. l is a vertical transverse section of the wall from floor to ceiling.

Fig. 2 is a sectional View taken on a line 2 2 of Fig. l.

Fig. 3 yis a perspective view of my improved plaster lath stud and nailing blocks, showing the same about one-half actual size.

Fig. d is a sectional vview showing a modified method of positioning the stud over that shown in thc other views.

In carrying out my improved invention, instead of using the conventional small channel iron stud I use a strip of the wall board l of a length preferably suiicient to reach from the floor 2 to the ceiling 3, and ot a preferable width sutlicient to equal the stud space allowed for the wall plus an interlocking edge for the plaster, as will be presently described more in detail. As indicated, this stud strip of plaster board is of that type (shown in detail in F ig. 3) wherein a center core l of calcined gypsum, with or without a filler material of sawdust or the like is adhered and secured to two sheets of heavy surface paper as at 5 and 6. As

`manufactured andV used this plaster board has been proved by underwriters tests to be substantially lire proof, and it is very sti and rigid in its nature.

To each side of this plaster lath stud I nail or otherwiseL secure in preferably relative staggered order, a number of nailing blocks or cleats 7 ot wood or the like of a length equal to the space desired betweeny pear.

In practice the plaster board studs 1 with their attached blocks 7 are suitably fastened to the Hoor .andv ceiling in a position edgewise to the plane of the wall. This also presents the ends of the nailing blocks 7 to the plane of the wall so that sheets 9 of the plaster board or plaster board lath may be nailed or otherwise fastened thereto with the extended edges 8 of the plaster board studs projecting between the edges of adjacent sheets, leaving small interstitial spaces 10 between theV studs and the edges of the sheets. Plaster l1 is then spread over the whole face of the wall covering and embedding the plaster board lath and plaster board stud, and flowing into the interstitial spaces 10 around the studs and behind the lath sheets, thus binding and knitting and locking the whole into one lunitary wall structure, when the plaster has dried and hardened and set.

Thereafter should the blocks 7 be destroyed by fire or deterioration, the unitary wall made up of the studs, lath and plaster will remain and be as strong, durable and lire proof as is required of this type of wall. 'ffl Vhile I have preferably shown the stud l as projecting between the adjacent edges of the lath sheets, still in practice the reverse structuremight be used as shown in Fig. 4; where the stud la could be stopped short of the spaced adjacent edges of the lath sheets 9a, and the plaster l1a will squeeze in between the lath sheets and around the stud as at 10a, thus uniting and binding the whole together.

While in the interestof economy and eficiency, I preferably make the stud l of the plaster board, still in practice the main desideratum is to provide the temporary nailing blocks so that plaster board lath can be used cheaply and effectively. Hence it follows that any thin, iire proof stud member set in edgewise to the plane of the Wall and carrying the nailing blocks may Well be substituted yfor the plaster board stud without departing from the spirit of the invention.

From the foregoing` description it Will be readily seen that I have produced such a device as substantially fulfills the objects of the invention as set forth herein.

Having` thus described my invention what I claim as new and useful and desire 'to secure by Letters Patent is:

1. A Wall stud compr-isi'ng` 'a thin flat member, and nailing blocks secured to the fiat faces of such member.

2. A Wall stud comprising a thin fiat member, and nailing blocks secured to the flat faces of such member, the edges of 'the flat member projecting beyond the ends of the blocks.

3. A Wall stud comprisinga thin flat member, and nailing blocks secured to the flat yfaces thereof and in spaced relation.

4;. A Wall stud comprising a thin flat member, and nailing blocks secured to the flat faces thereof and in spaced relation, the blocks on opposite faces of such member being disposed in relatively staggered relation.

5. A building stud comprising a strip of thin flat plaster -Wall board, and nailing` blocks secured to the flat faces thereof.

'6. A Wall stud comprising a thin flat member to be disposed transversely of the plane 'of the Wall, and nailing blocks on the flat surfaces of the flat member, the nail receiving surfaces of the blocks lying parallel' to the Wall.

In testimony whereof I affix my signature. A
